    Purpose of use
    To gain knowledge and how to find a radius when given only the area of the circle
    Comment/Request
    Please help me calculate the radius with the area given

    Purpose of use
    Too lazy to do the calculation myself, simulating a perceived area of another geometric shape into what the given circular radii would be.
